I find it curious when this sort of question is asked. There seems to be a presumption that a composer may only be as good as what they have done already and couldn’t do something novel.
(I have had a few glasses of wine and may be a bit argumentative.)
I am sure that there weren’t many who thought that Howard Shore was a bizarre choice for Lord of the Rings (and, perhaps, hadn’t heard Looking For Richard but couldn’t see how that style would have been a good fit for Middle Earth).
